Description
Technical Field
The invention relates to the field of lithium batteries, in particular to a method and a device for detecting the orientation of a coating diaphragm on line.
Background
The lithium ion battery consists of a positive plate, a negative plate, a diaphragm, a tab, electrolyte and an outer package, wherein the diaphragm is mainly used for separating the positive plate from the negative plate so as to block electrons and allow lithium ions to migrate. In order to improve the hardness of the battery cell, prevent the battery cell from deforming during the circulation process, and increase the safety performance of the battery cell, it is necessary to perform a surface treatment on the separator, which is usually to add a functional coating to the separator, such as: ceramic coatings, PVDF coatings, etc. Currently, the membranes of the lithium battery industry can be divided into four categories according to the coating: uncoated diaphragms, single-sided coated diaphragms, double-sided same-coated diaphragms and double-sided different-coated diaphragms; the uncoated diaphragm and the diaphragm with the same coating on the double surfaces do not have the orientation problem, but the diaphragm with the single coating and the diaphragm with the different coating on the double surfaces have inconsistent two surfaces due to the addition of the functional coating; the influence of the orientation of the membrane on the performance of the cell is great during the use of the coated membrane.
Generally, the coating face should be facing the positive electrode, i.e. facing the positive electrode; such as: when the single-sided PVDF membrane is used, the membrane coating surface needs to be opposite to the positive plate, so that the membrane and the pole plate can be well bonded; if the diaphragm coating surface corresponds to the negative electrode, the diaphragm and the pole piece are not adhered, the hardness of the battery cell is reduced, and even the battery cell is seriously deformed. It is therefore important whether the coating face is oriented correctly or not.
At present, when the coated membrane is used in the industry, the orientation of the coated membrane is mainly determined by a mode of identifying the appearance of the coated membrane through the experience of staff, but the method has the following defects:
1. the orientation of the coating diaphragm is subjectively judged by staff, and is influenced by staff experience and responsibility, and when the staff experience is insufficient or the responsibility is not strong, the missed judgment or the wrong judgment can be caused;
2. the appearance difference of two surfaces of a part of coating diaphragm is extremely small, the part is difficult to be identified by naked eyes, misjudgment is easy to cause, and 100% of correct identification cannot be ensured;
3. accurate data information cannot be formed and cannot be traced through subjective judgment of staff;
4. when the staff misjudges, the staff is not easy to perceive, the large-batch production of bad batteries can be caused, the raw materials are seriously wasted, and the production cost is improved.
In view of the above, it is necessary to provide a technical solution to the above problems.
